Miniature rose plant-Schobitet variety

ABSTRACT

A new and distinct variety of rose plant of the Miniature class is provided which forms in abudnance attractive fully double flowers which are clear yellow in coloration. The plant is low growing, compact, well formed, and possesses semi-glossy foliage. It performs well as an outdoor garden rose, or it readily may be forced into bloom while growing in a greenhouse.

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant of the present invention was theresult of plant breeding program wherein the resulting progeny werescreened for the desired characteristics.

As the result of this breeding program, a new and distinct rose varietywas produced which is distinguished from its parents as well as from allother varieties known to the originator.

The new variety of Miniature rose plant of the present inventionpossesses the following combination of characteristics:

(a) a vigorous growth habit which forms a well-balanced, well-branchedplant which commonly attains a height of less than 60 cm. and hassemi-glossy foliage which exhibits greater than usual diseaseresistance,

(b) produces fully double, well-formed flowers of clear yellowcoloration, fading eventually to pale lemon yellow coloration, which areof good substance and which are produced in abundance, and

(c) has an ability to be used either as a fully hardy outdoor gardenrose, or to be forced into bloom in a greenhouse as a flowering potplant.

In view of these characteristics, the new variety meets the needs of thehorticultural industry for all purposes, and is particularly versatile,being well-suited to either outdoor garden or indoor greenhouse culture.

Asexual reproduction by cuttings and budding has been accomplished atWest Grove, Pa. Succeeding propagations have shown that the uniquecombination of characteristics is fully established and is transmittedto successive generations.

The new variety has been named the SCHOBITET variety. This new varietypresently is being marketed by the Conard-Pyle Company of West Grove,Pa. under the ROYAL SUNBLAZE and MINIFLORA trademarks.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows typical specimens of the new varietyof Miniature rose plant of the present invention during early July asdepicted in color as true as is reasonably possible to make the same incolor photograph of this nature. The specimens illustrated were buddedon Rosa multiflora understock and were grown outdoors in a cultivatedfield at West Grove, Pa.
